Iko Uwais, star of the phenomenal The Raid Indonesian action movie series, is the latest addition to Star Wars: The Force Awakens. Watch Uwais in this fight scene from The Raid 2: Berendal and just try not to be excited.

Uwais, along with The Raid costars Yayan Ruhian and Cecep Arif Rahman, are apparently performing fight work for the movie, which is already done with principle photography. I'm going to go out on a limb here and guess they're doing motion-capture for some of the film's CG characters (hey, it's not like everything is going to be a practical effect), but it's possible they're playing characters who for some reason have to do a lot of fighting yet somehow didn't need to shoot any scenes with the film's leads. Either way, Twitch puts it pretty well:

[J.J. Abrams] has now also cast a trio of highly skilled martial artists who have already demonstrated their skills with blades, batons, etc in a world where super powered warriors fight with blades, batons, etc.
